I carelessly invested in a stock on a spike near the peak price. How can I salvage my investment?
It would be useful to forget about the initial price that you invested - that loss happened, it's over and irreversible, it's a sunk cost; and anchoring on it would only cause you to make worse decisions. Getting "back" from a loss is done exactly the same as growing an investment that didn't have such a loss. You have x units of stock that's currently priced $46.5 - that is your blank slate; you need to decide wether you should hold that stock (i.e., if $46.5 is undervalued and likely to increase) or it's likely to fall further and you should sell it.   The decision you make should be exactly the same as if you'd bought it a bit earlier for $40.
