The DJIA has risen 25%... in round numbers from 20,000 to 25,000. That 5000 point gain is 25% higher than where it started. A good year by any standard. But as the DJIA rises it requires larger and larger increases to bring equal returns. From 5,000 to 10,000 is a 100% return, from 10,000 to 15,000 is a 50% return, from 15,000 to 20,000 is a 33% return... all 5000 point gains but each has a diminishing return.
In 1975 the DJIA opened the year at 616 and closed the year at 852. A rise of "only" 236 points but it was a 38% gain on the year.
Since 1975 there have been 8 other years with 25% or higher gains...75, 85, 89, 95, 96, 99, 03, 13.
This website here does a good job showing market performance by POTUS.
All this said, I would be careful trying to take credit for market gains as market losses could be right around the corner.
