Lise, I agree with Louisville, I'd just leave the GE stock alone until it's time to access the pension fund. It pays a nice dividend and barring another financial crisis, it probably won't suffer a big drop. It was hit hard during 2008-2009 as just about every stock was, and they are still standing today and probably will be for another 100 years. One could argue that they are better off now than they were before the financial crisis since they have largely divested itself of the finance arm of the company, and focusing more on its core industrial operations.
As far as REITs are concerned, be mindful of where you hold them. It's generally better to buy them in a tax-advantaged account (Roth or Traditional IRA) as opposed to a taxable brokerage account because of the high dividends they pay, and the fact that those dividends count as ordinary income on your taxes. Also, be sure to do your DD on which to buy. You can do really well with a quality REIT, like Realty Income (O), but a bad one can put a damper on your portfolio. I would put no more than 10% of your entire portfolio in REITs.
I hope this helps, and good luck!
