Hi Toof, Re: AIMing the Basket while still AIMing the holdings........
Mr. L always said AIMing the basket was the simplest. You could execute AIM trades on the individual holdings when they are indicated and still run a 'macro' view. AIMing the overall investment to keep it under control would possibly provide extra liquidity while awaiting recovery of individual holdings to their respective selling points.
For tax loss harvesting purposes isn't general advice to sell all holdings that are below cost near to the end of the financial year and either accumulate/carry such losses so that future/other capital gains can be taken more tax efficiently, or use the loss to offset capital gains elsewhere.
When tax harvesting in such a manner you have to be mindful of 30 day trading rules, so commonly you buy another similar asset instead of repurchasing the same asset (or be out of the asset for 30+ days before repurchasing the same asset).
Perhaps a opportunity to consolidate a number of individual stocks into a broader fund/ETF.
I know of some who've accumulated massive amounts of losses simply by letting winners run, tax harvesting losers, such that if a enforced or otherwise capital gain does occur the tax pain is reduced/eliminated.
