Sorry, no.  There's not a way to make up for "dog" investments.

But your $10,000 is now worth over $19,000 in only five years, so I'd say you don't need to change anything.  Your good picks have gained far more than your dog has lost.

Interested in a 529, for instance if you wish to invest more than the $2000 ESA annual max?  No problem, you can have an ESA ~and~ a 529.
