We can look back at every downturn in share price and speculate how we could have sold high and repurchased lower and increased our share position. The latest downturn won't be the last in the future of this company, I can promise you that. At every one in the future, we'll be able to look back think about what might have been if we'd simply traded our shares. The ability to second guess ourselves looking in the rear-view mirror will always be there.

If you got into this investment with trading in mind, then by all means do it. If you're like me and you invested for the long term, choosing to ignore the short-term swings (except to buy more shares when the price drops), then the focus should be on the road ahead and not the rear-view mirror.

We each have to simply decide which type of investor we are. Some choose to focus on both, holding a long-term core position and trading the rest. Don't beat yourself up for sticking to your original goal with the stock. If your strategy changes, then act accordingly.

When the LymPro partner is announced and we have a defined path to commercialization with more accurate revenue expectations, the recent drop will be less important. You can choose to view the recent drop as a missed opportunity, or an opportunity to buy more cheap shares.
