> The prices of the securities are based on what investors think the company That's a quaint view, but the logistics is completely mathematical. The prices of securities is absolutely and completely based on the bid and offers. It is a completely mathematical outcome of transactions. Of course, prices feed into the psychology of investors, as well as their estimates of future performance. But a huge amount of cash in the market is there to make short-term profits, not long term profits. Automated systems trade huge amounts of money based off technical analysis and price prediction on multiple timescales. There are computer systems with stupid amounts of computational power who only think about how to make two cents by being ahead of the market by 1 millisecond, 1 second, one day, one week. And they make billions. > That’s why in really uncertain times the stock can drastically move without any of the current financials changing drastically. I think we're into a rathole here, but this statement basically contradicts your earlier point. If prices are based off the future 6-12 months from now, then crashes wouldn't happen, or be so severe. This is obviously false. Bubbles pop violently.
