The market has always had cycles of peaks and valleys, but these began to be closer together when retail buyers gained access to direct trading, eliminating a flesh and blood broker who would act as an intermediary. Volume trading quickly went parabolic as retail and institutional investors gained instant access, then came after market trading.
New products offered by brokerages have over-leveraged the market, making peaks and troughs more intense stoking volatility. See the history of the 2008 crash.
I am not saying this is an indicator of "the time of the end". I think that more access without much needed trading rules has created a violently rocking market that most retail investors no longer trust. "It is rigged" is a common criticism among such investors. The SEC could stop congressional members from insider trading, but they will not. Insider information is a primary incentive for being in congress. Show me a member of the House or Senate who was in worse shape financially after serving, and I will send you a picture of the Bigfoot that lives in the woods behind my home wearing a smoking jacket.
Long positions in the market are risky. Ask Warren Buffett how much he has in 6-month T-Bills.
