Schedule C for personal investing

I took a second mortgage and have invested the proceeds in a number of investments - some small and some larger.  There is a mix of long and short maturities and some cash is invested in money market funds.  I continue to spend considerable time monitoring the investments and investigating new investment opportunities.  There is a mix of K-1 and 1099-INT investments.  There is a semi-liquid market for some (but not all) of the K-1 investments so I can sell some of them if I want to do so.

 

Are these facts supportive of me tracking the income/expense of these activities as a Schedule C business?    Thanks!
