Here's how the DY holding has behaved with inventory management of shares since Sept of 2019.
(Price/Share up 28.6% since the Start; Account value gain 50.5%; Cash Reserve up 195%)
Stock selection is important but I feel inventory management and risk control is also. First came the completely unexpected decline related to the Coronavirus outbreak. I'd set aside about 25% of total at the start for downside averaging should the price decline first. That proved to be fortuitous. I bought shares to exhaustion of cash during the decline. That cash and the buying it allowed led to a 52% increase in total share count.
As the image shows, from the time the price bottomed out a year ago to the first sale at the end of May, 2020 the value at risk grew a bit. However, after that, the value at risk remained nearly constant and share inventory was trimmed as the price/share continued to rise. The last sale was at just over $100/share.
With a discount of around 30% from that last sale I added 12% more shares back to the holding using some of the accumulated reserve of cash. If DY continues to decline I can continue buying back inventory. Should DY turn back upward and the cash proves to be not needed, I can always take some of it and start something new as an investment.
