Comparing between stocks which has ups and downs, versus slow growing but constant dividend payout like bonds?

It really depends on your age and your risk profile (aggressive or conservative). If you are a young adult and are more aggressive, go for more stocks that would generate higher but less stable returns in the long run. If you are an elderly who has reached retirement and are more conservative, go for more bonds that would generate lower but more stable returns in the short term. Just my humble opinion.

They are totally different beast. We can't compare apples to oranges. Bonds can be even more exotic than stocks; Some stocks can be as steady as most bonds. Bonds doesnt mean is safe, stocks doesnt mean is risky. It just depends what u are looking at, what u are looking for, and what are they for.

The question should be about your risk profile, what do u understand, and what u are comfortable with.
