How does a robo advisor manage your funds?

Yes, it does not matter.

TL;DR

Yes, it doesn't matter. it allocates based on your risk index. But it doesn't buy specific stocks but ETFs. Also re-allocation does not happen frequently.

Hello! Here's how stashaway works, rather than deciding whether to buy more shares of General Motors or General Electric, they determine how much we should allocate towards North American Large Cap Equities versus Emerging Market Equities, Long Term Government Bonds or Gold, for example.

StashAway will re-optimise a client’s target portfolio in the case that there is a change in economic conditions. Investors can expect changes driven by this event to occur every 3-7 years, and for the changes to the portfolio to be significant. In turbulent times (e.g., 2008 Financial Crisis), changes to a portfolio could be more frequent than once every 3-7 years; in fact, changes would have occurred multiple times within the year leading up to the financial crisis: four changes of regimes between November 2007 and February 2010.
