Strategy for investing large amount of cash
Getting the right diversity of investments helps buffer you from some of the short term market swings. If you need advice it's worth spending a small part of that money on a consultation with a financial adviser, who can talk to you about your goals, your time horizon, and your risk tolerance and recommend a good starting distribution. (Free advice from brokers risks being biased by their commissions.) Once you have that plan, uou need to decide how to execute it. Low-fee index funds are a good way to get started until you learn more, and for many of us that's all we ever need. Then you need to decide whether to invest it all at once or dollar-cost average. I've heard arguments both ways; DCA does mean you risk missing some immmediate gains, but also reduces your risk of buying at a temporary high and taking some immediate losses. For me DCA seemed to make sense, but that's another decision for you to make.
