I don't know what stocks they are, how much you paid, or how much you know about the fundamentals of each company.
I'm more into individual stocks than the average MMM-er, but it's more for personal reasons than thinking I'm smarter than all the six-figure analysts. I find it is difficult to be knowledgeable about more than a few, even with a lot of time invested (relative to my "spare" time as a full-time wage earner, military reservist, and startup business operator). So even if I knew your portfolio, I'd be unlikely to have a good answer.
One question you might ask is, relative to your overall Stash, is this money you can afford to lose, or is there a benefit to parking it in more secure assets right now? If losing what's left would hurt, I'd suggest cutting your losses. If you have the means to suck it up, let it ride and enjoy the lesson.
It's easy to sit here any say sell them, and consider the losses tuition, but obviously you have to make your own decision.
On the upside, you get to write off the losses on your taxes!
I do?
All of it is in a tax free savings account: TFSA.
Then, no. Sadly. Downside of deferring tax on gains.
