Newbie Options Trading Questions

[SlowStroke]

1) The Situation

I spot an upward trend in stock XYZ. The stock price is $80. If the price falls to $78 I will admit I was wrong and exit the trade. If I am correct the upward trend may last more than a year and I will stay in for the duration.

2) The Problem

To purchase a block of 100 shares will cost $8000. The amount of risk I am willing to assume is 2% which at the current time means I can only afford to buy 15 shares.

3) Options Solution?

I don't know anything about trading in stock options. But I suspect it may provide a solution to this problem.

4) My Questions

Is there any way I can purchase stocks in blocks smaller that 100 shares?

Is there an options trade that will simulate the risk to reward ratio I want based on the price movements of stock XYZ?

What if the upward trend lasts for several years? How do I roll over or extend the options trade to take advantage of this?

5) Thanks

Thanks in advance to all who reply. I hope the questions aren't too basic. I'm here to learn.
