Funny similarity here.
A US bio-team synthetically creates "life from life", as their motto goes, and naysayers from Canada's ETC Group (unfortunate acronym) respond with this:
"Synthetic biology is a high-risk, profit-driven field, building organisms out of parts that are still poorly understood."
Poorly understood by whom? Because the ETC don't understand the complex and internal structure of biological science does not invalidate it.
Back to the markets, which are driven by emotion which is patterned and complex, but readable, unlike tea leaves:
Markets follow distinctive albeit sometimes confusing patterns. That you don't understand this is as immaterial to the reality of markets as it is for the ETC to say "we don't understand complex biology" so it must be inherently wrong, not to mention dangerous to utter these words!
The bellwether of today's sharemarket, the Dow, has up until recently traced out almost exactly the same pattern as the Dow did after the (initial) crash of 1929. There were many aftershocks, many secondary crashes, most of which were far worse than the initial crash.
The initial retracement back then was a 50% correction, which the media of the day reported as proof the crash was over. Pretty much immediately after that timely but wrong call, the market lost roughly another 90% of its shattered value.
How does a market lose 90% when it's down half already? Well, 90% of 50% is about 95% of the original 100. It happened. Look it up.
Today's correction has been 62% and, as then, the mainstream media recognize this as the signal for the crash to be over. Of course, they're always right. That's why you were buying real estate, isn't it? Nonetheless, the probability is very high for major downward movement in the immediate future.
For today's naysayers, this is not "understood".
PS How does this thread have anything to do with aviation? Are you serious??? Were you awake in 2008/9?
