You may be looking for a simple answer to a simple question, but without more information it's difficult to provide an answer. For instance, how does this new fund fit in with your overall asset allocation. For optimization and efficiency, we generally suggest investors view their entire portfolio as one. In doing this your taxable investments should be tax-efficient and integrated into the whole portfolio. As a stand alone, or for another goal in 10-15 years, 100% stock would not be recommended. If this is part of retirement and only part of your equity AA, then it could work. However, in that case, I'd probably recommend total stock market. Again, the recommendation would depend on the rest of your portfolio.
