Mainly caused by 'volatility' on the drop. I just want to be clear... I was speaking about short term, and not long term relevance. Earlier I was saying I prefer to go into stocks, particularly biotechs that have at least 1 Yr+ cash to off set cash burn of 1 year. My rule of that is based on relationship to short term trading. I'm a short term trader... Very short term. I just emphasize that the 1 year rule of cash on the books for companies is a good rule. It substantially reduces the risk of any near term sudden surprises of 'cash raising stock offerings', which usually will crash a stock, even at over sold levels (such as STEM & AKBA as recent examples).
But my view is that AKAO is likely safe using the 1 year of cash rule.
