VOO and SPY are basically the same thing, SPY is older and structured as a trust, VOO is an ETF. Both track the S&P 500. They'll probably recommend some combination of equity and bonds, probably a split between VOO (slightly lower fees and more efficient payout of dividends -- I do mean slightly) and TLT (20+ year treasuries).

VOO and TLT have limited correlation as treasuries are seen as a safe-haven. We've seen huge spikes in treasury funds recently, since they go up in value when interest rates go down. It's a bit unintuitive, but treasury funds have to cycle through their holdings over time to track the index, so when interest rates on new issues go down, older issues command a premium in the amount of pre-paid interest.

VOO is the same index as SPY (SP500), so that can't be it. Maybe you meant BND, a highly popular total bond market ETF that would be for the risk-intolerant?

Maybe VTSAX?
