Why is it, then, when we take those Greek words to the Bible, somehow, it appeals to us that we must transfer the literal from the symbols to the more simple teaching? Why is it that, to us, the last destruction has all the ear-marks of a literal one? The shaping and forging of the evidence, caused all scripture to bow meekly to a few metaphorical texts, which anticipated a reversion of all these same words used in the plain, simple instruction to God’s people

Even if the normal expectation for a market is mean reversion and reversal (as it is in the short term for equities), there is usually at least a slight edge for continuation out of areas of volatility compression
23.
Part Two has taken the basic forces driving price movements—mean reversion and range expansion—and has begun to put them in the context of actual, practical market structure
24.
There are two competing forces at work in the market: mean reversion and range expansion
25.
There could be some debate, but good places to start would be mean reversion in overextended markets, especially following climax moves; the interface between pullbacks and new trend legs, or the point where new with-trend momentum emerges out of a pullback; higher time frame drives to clear target areas; and failure tests at the extremes of a range, ideally with signs of accumulation or distribution
26.
Being aware of higher time frame overextension and potential exhaustion is one tool that can help traders avoid trades that immediately fail and collapse under the force of higher time frame mean reversion
27.
If you choose to develop a systematic trading plan based on relative strength, you will also need to consider the impact of mean reversion
28.
Though the concept of being long the strongest markets by relative strength and short the weakest is sound, there are the twin forces of mean reversion and range expansion to consider
29.
Though it is a gross overgeneralization, currencies tend to trend longest and best, commodities are somewhere in the middle, and equities are more prone to mean reversion and reversal than long trends
30.
The fact that a market can consolidate near the highs of a large thrust (meaning that mean reversion has failed in this case) is strong evidence of underlying buying pressure
31.
The balance of mean reversion and range expansion is a little different in some time frames, but technical tools retain their validity even at long time horizons
32.
There are strong statistical tendencies for mean reversion, and traders working a disciplined approach to fade trades may find that they can achieve higher returns and more effective deployment of capital, albeit at the expense of much harder work and many more transactions
33.
The VIX is all about mean reversion

Mean reversion is a common volatility characteristic of almost all traded underlying contracts
46.
“So an example for me would be that since an index like the S&P 500 is primarily a reversion to the mean type instrument, then once I can see through historical price action that the 75 RSI acts as resistance for advancing prices in the majority of circumstances, that is a great spot to initiate a short play as a reversion to the mean system trade?”

Long-horizon studies presented evidence of mean reversion in stock prices, although it turned out that such long-horizon analysis is plagued with econometric problems
51.
I will show later that trend-following strategies are profitable for many risky assets in the short run, while value strategies, which may in part rely on long-term (relative) mean reversion, are profitable in the long run

• Time variation in the profits/GDP ratio might be more predictable, given its apparent mean reversion tendency
53.
Even simple single-factor term structure models capture the idea of mean reversion but such models assume that the longest rates are constant
54.
Detrending is consistent with the mean reversion story because the past decade average is a plausible anchor for mean-reverting rate expectations: the wider the gap between the current short rate and this anchor, the stronger the market’s expectation of normalization (as long as the central bank has sufficient credibility that yields well above the past decade average are not taken as a signal for much higher future inflation)
55.
) Limited data hint at relative mean reversion tendencies across sectors: if a style is successful over multiple years and there are substantial inflows into it, future return potential may be reduced

Statistical evidence suggests that many financial asset returns exhibit positive short-term autocorrelation (momentum bias) and negative long-term autocorrelation (mean reversion bias), as Exhibit 20
59.
There is also some evidence of long-term and short-term mean reversion: high past returns one to five years ago or during the past week predict low future returns
60.
Valuation changes are important in accounting for realized returns, but the impact on return predictions is often modest because mean reversion tendencies can be weak
61.
It is more reasonable to assume some mean reversion if prevailing valuations are exceptionally high or low
62.
In the absence of better value anchors, investors may use average real market price over the past few years to capture any mean reversion tendency
63.
I simply remind the reader that all such secular trends, if persistent, create potential landmines for backward-looking mean reversion or fair value models (see Section 12

It can also reduce the regret associated with mistiming purchases and it may benefit from any mean reversion in aggregate market valuations
66.
However, excluding the mean reversion argument (on which empirical evidence is weak), standard finance theory says that dollar cost averaging is suboptimal
67.
A negative autocorrelation defines so-called mean reversion, meaning that an above-average return tends to be followed by a below-average return and vice versa
68.
The concept of reversion to the mean is not original by any stretch of the imagination
69.
There are a few key things to know about the squeeze in relation to the reversion to the mean trades, as well as some general tips on how I utilize this setup

For the reversion to the mean trades, there are examples at points 3, 4, 5, 6, and 7
71.
At point 5, a squeeze fired off short, and it turned out to be a very quiet trade, in essence a normal reversion to the mean trade
72.
Now that we have covered reversion to the mean, it’s time to dive into the squeeze
73.
If the exit rule for a losing trade is based on price, one can rely on the fact that the swing trade is expecting a reversion to the mean, and therefore the price are varying within a channel
74.
We believe in reversion to the mean, so it can make a lot of sense to invest in a distressed sector when you find good businesses whose public shares trade inexpensively relative to their earnings in a more normal environment

77.
That she had been carried off her feet by the strength of the young giant when his great arms were about her in the distant African forest, and again today, in the Wisconsin woods, seemed to her only attributable to a temporary mental reversion to type on her part—to the psychological appeal of the primeval man to the primeval woman in her nature
78.
The tendency to reversion may often check or prevent the work; but as this tendency has not prevented man from forming by selection numerous domestic races, why should it prevail against natural selection?
79.
There may truly be said to be a constant struggle going on between, on the one hand, the tendency to reversion to a less perfect state, as well as an innate tendency to new variations, and, on the other hand, the power of steady selection to keep the breed true
80.
That the struggle between natural selection on the one hand, and the tendency to reversion and variability on the other hand, will in the course of time cease; and that the most abnormally developed organs may be made constant, I see no reason to doubt
81.
All being mainly due to the species of the same group being the descendants of a common progenitor, from whom they have inherited much in common, to parts which have recently and largely varied being more likely still to go on varying than parts which have long been inherited and have not varied, to natural selection having more or less completely, according to the lapse of time, overmastered the tendency to reversion and to further variability, to sexual selection being less rigid than ordinary selection, and to variations in the same parts having been accumulated by natural and sexual selection, and thus having been adapted for secondary sexual, and for ordinary purposes
82.
As all these marks are characteristic of the parent rock-pigeon, I presume that no one will doubt that this is a case of reversion, and not of a new yet analogous variation appearing in the several breeds
83.
After twelve generations, the proportion of blood, to use a common expression, from one ancestor, is only 1 in 2048; and yet, as we see, it is generally believed that a tendency to reversion is retained by this remnant of foreign blood
84.
If, for instance, we did not know that the parent rock-pigeon was not feather-footed or turn-crowned, we could not have told, whether such characters in our domestic breeds were reversions or only analogous variations; but we might have inferred that the blue colour was a case of reversion from the number of the markings, which are correlated with this tint, and which would not probably have all appeared together from simple variation
85.
It is a case almost certainly of reversion
86.
Any part or organ developed to an extraordinary size or in an extraordinary manner, in comparison with the same part or organ in the allied species, must have gone through an extraordinary amount of modification since the genus arose; and thus we can understand why it should often still be variable in a much higher degree than other parts; for variation is a long-continued and slow process, and natural selection will in such cases not as yet have had time to overcome the tendency to further variability and to reversion to a less modified state
87.
Although new and important modifications may not arise from reversion and analogous variation, such modifications will add to the beautiful and harmonious diversity of nature
88.
We must by no means overlook the effects of the definite action of changed conditions of life, of so-called spontaneous variations, which seem to depend in a quite subordinate degree on the nature of the conditions, of the tendency to reversion to long-lost characters, of the complex laws of growth, such as of correlation, comprehension, of the pressure of one part on another, etc
89.
Of these latter variations several may be attributed to reversion; and the characters which thus reappear were, it is probable, in many cases at first gained in a gradual manner
90.
This rare event is probably a case of reversion to the long-lost, aboriginal instinct of nidification
91.
Moreover, Gartner expressly states that the hybrids from long cultivated plants are more subject to reversion than hybrids from species in their natural state; and this probably explains the singular difference in the results arrived at by different observers
92.
Thus Max Wichura doubts whether hybrids ever revert to their parent forms, and he experimented on uncultivated species of willows, while Naudin, on the other hand, insists in the strongest terms on the almost universal tendency to reversion in hybrids, and he experimented chiefly on cultivated plants
93.
The process of this reversion in Olenin is hastened, of course, by love for a Cossack woman, one of those clean-minded girls who think no harm in a kiss or caress, but whose virtue is an absolute and natural thing that admits of no question or discussion
