I am not a trader (I know myself well enough to know I don't have the temperament) and have had good success over my adult life identifying, studying and investing with the emerging multi-year macro trends.
I started buying what I considered very cheap inflation protection (essentially "insurance") early last year, and got more aggressive with that strategy when the COVID spending started ramping up in March and April. Other themes that are driving my portfolio at this time, long term, are the electrification of economies globally, and the potential for EM to outperform as the global economy finally starts to recover from the virus.
Bought gold, silver and copper miners to start. Some materials companies. Added aluminum and nickel a bit later. Missed the lumber play though. Sold down (reduced) positions and increased cash significantly a couple of weeks ago after the run some of the companies, such as FCX, have had. The nuttiness going on right now (e.g. GameStop/GME, etc.) looks (to me) like it might be the classic blow off indicator of this secular market cycle topping, so imo time to be more careful.
FWIW, I don't think the inflationary outcome thesis has been confirmed yet. There's plenty of deflationary/dis-inflationary forces active and in play at the moment, including increasing business closures/failures, capital destruction and permanent job/income losses.
An inflationary outcome implies a continued fall in the US$ exchange rate. Right now that's the consensus; but what if the US$ surprises the other way? The US 10-30 year Treasuries are the only developed economy sovereign bonds, other than gilts, currently paying a nominal interest rate that's much above zero (1.11% and 1.83%, respectively). If (when?) we get another international safe haven capital flow event it'll be USTs being bid. Heavily. All it would take is something like the underperformance of the vaccine efficacy, or a virus mutation that negates most or all of the available vaccines.
