Great thread!
I have a rewards MC that pays back 1%. It's not the best rewards card out there, but it has a $35k limit, and I don't really have the patience to apply for others. I'm an expat living overseas, and it's a real hassle to arrange to forward new cards delivered to my US address. Likewise it's a hassle to wire funds to my US brokerage account. But I can pay my US credit card bill from here without any trouble. So Loyal3 should be very convenient for me.
Normally I invest about $7.5k/month from my salary. This will go up to $10k at the end of the year, if all goes well. For this month's investments, I went ahead and set up an account with Loyal3 (which was fast and easy) and bought:
BRK.B $2,500
UL $2,500
MAT $2,500
It's an interesting idea to use Loyal3 for churning, but since I'm trying to stick to a long-term investment strategy, I'm not planning any buy/sell transactions solely to capture the rewards points. I should get plenty of points from my normal purchases. Also I have about $74k in AAPL that I've held for nearly a year. When the 1-yr holding period lapses, I may dispose of that position and reinvest through Loyal3, which should give me a nice 1% kicker on my return. I'm not sure whether Loyal3 will view my trades as "not in line" with their platform, given that I'm buying and not immediately selling. But if I'm cut off from CC purchases, it won't cost me anything. I'll have stock that I was planning to buy anyway, the points from prior purchases, and I'll even be ahead a bit from not paying trading commissions, which are $8.95/trade with my usual broker. Seems a great deal. To bad for the $2,500 per stock restriction, though. If not for that I'd load up on BRK.B.
