Check on logical theory arguments such as slippery slope theory/fallacy, I've noticed I sometimes think that myself, when a stock I own falls, maybe there is a technical level, I sometimes get scared thinking it will keep going lower but usually when I feel that, it's some sort of bottom in the stock, you think everything will keep compounding on itself sending the share price lower but that usually does not happen but a lot of investors are thinking it or feeling it and they are all wrong sending the price lower on irrational fear but it's a good buy. Maybe that was not true in the past but central banks are always at the ready with more liquidity in the markets and the shares will go up, another thing with Australia unable to compete in the Nickel market, it's a sign the AUD may have to be devalued.
