I know there's a longstanding discussion here about the merits of VTWAX vs VTSAX, but I'm here to ask a potentially dumber question. Considering VTSAX ($157) is trading at 3X VTWAX ($49), does it make sense to shift my buys to VTWAX, given that I'd be able to simply buy *more* with each individual contribution to my investment fund. If you split a $7,500 ROTH IRA over 26 weeks ($288), you'd be getting nearly 6 full shares of VTWAX vs only 2 of VTSAX. I do know that expense ratio is a half-point higher for VTWAX (.09% vs .04). Now, someone please tell me why this is stupid and kindly explain how things actually work. Thanks!
