Options are an indication what a particular segment of the market (those who deal a lot in options) think will happen. (and just because people think that, doesn't mean it will) Bearing in mind however that people writing covered-calls may due so simply as part of a strategy to mitigate downside risk at the expense of limiting upside potential. The presence of more people offering up options is to a degree an indication they are thinking the price will fall or hold steady, since that is in effect the 'bet' they are making. OTOH the people buying those options are making the opposite bet.. so who is to say which will be right. The balance between the two and how it affects the price of the options could be taken as an indication of market sentiment (within the options market) as to the future direction the stock is likely to take.
(I just noticed that Blackjack posted the forumula that can be used to model all of this)
To address the last part of your question 'does that mean it will go lower' I would say this. The degree to which any of this puts actual pressure on the stock of the underlying instrument is highly debatable, since many (likely most) people trading in a stock never look at what the options for that stock are doing, but base their decision on other factors such as price history, momentum, fundamentals and recent news about the company. To presume that actions in the options market would put pressure on a stock price, you would need to believe that a signficant fraction of the buyers and sellers were paying attention to the options market. Which might be the case for some Quants, but likely not for a lot of other buyers.
And it could be argued even then that both groups, those trading options, and those trading stocks, are both looking at the same information to make their predictions of the likely future for the stock, and thus even if there is a correlation between what the stock price does in relation to options, there is no real causality that can be established. We would in fact predict that given access to the same information, both groups would by and large be taking similar parallel actions due to coming to similar conclusions regarding the future price of the stock.
What is far MORE likely to pressure the price would be just the shear number of buyers or sellers, and also (especially since repeal of the uptick rule) someone who is trying to actively drive down the price via a lot of shorting at progressively lower prices. (something that is alleged to have been carried out by some hedge fund managers in the course of 'bear raids' on particular companies)
