Re: $500 promo from TD Ameritrade
Don't know, but you could always buy SHY or TIP.
Or just buy the same VG fund, pay the $50, and still come out ahead.
You could just put some stock shares you already own there, and trade a small amount of it several times, to reach Apex. Like swap 10 shares between XOM, C, etc, with low spread costs.
The thread I posted has other options, including an NTF money market fund.
Anyway, I'm not trying to convince anyone of anything, just thought this was an interesting way to make some $ from a broker that just bought a bunch of clients and then raised their prices.
