Both could go quite a bit further down, and depending on how LBT and the Board respond (layoffs, fab & product shutdowns, etc) to what will be a cut in the $8B China revenues, it is possible to revisit the single digits as last happened in the 2008 recession.
That's extreme and that path can be broken by a sufficient reaction by the company, so I'd suggest using the stock fund to cost average at the max 20%, then do direct investment below $15 and be willing to sit on it for a while.
Obviously, those who think the company will go BK or something are gonna stay short or whatever. Good luck with that.
I'm been trading around a fixed position, buying the new lows and quickly selling, and expect the volatility for the next few days to be large.
