RE:markets are so high I, as well as many others, am in the same position you are. It's tough to watch Loop go down slowly in sp while, like you said, the markets are soaring.
For myself, there is no small cap company I believe in more than Loop. As such, I'm taking advantage of the low sp to buy more shares when I can. You might look back and wish you bought more shares while it was still cheap, as I and most others here don't think it's going to stay at this level for very long - just waiting on a big NR (or multiple, as isn't unlikely for Loop) as well as a show of revenues.
There is obviously something to be said about a diversified portfolio. However, If you really believe in the company, the green will come. Loop is getting more exposure, more deals and more opportunity than ever. Once we have the right catalyst, Loop is going to make us all money.
Whether it is right around the corner or a few months down the road, I believe Loop will make up for the "missed profits" had one invested in something else until Loop was ready to soar.
Of course this is only my opinion, everybody must make their own assessment of their own investments, financial positions, how one plays the market etc.
