What I do is to determine without emotions major turning points and strong trends of major assets that include global indices, equity sector classes, high liquidity stocks, debts & fixed income, commodities and currencies.
Investing since 82. Felt the pain of the 87, 00, and 08 crashes. All fiat money is subject to devaluation. Most trading is now done by HFT-bots trading among each other. Won't chase any stock/ETF. Over 25 years experience as a networking geek.
