Insider Trading

i was thinking of ways it is done in the office. i ask myself was it ethical? it seems as if the company actually benefited from that. so what really happens... as a real estate company, we are always in the development to produce more communities to sell to the public/investors/end-users. we buy land, develop and a team will conceptualize on everything. once we have all the details and permits squared out we launch the project to the sellers. so the information during the development plans are very confidential. if it is leaked and we don't have the license to sell (LTS) from the Housing and Land Use Regulatory Board (HLURB), we are subject for a lot of misrepresentation and penalties. being part of the all the project teams, i get to know the information as early as the buying of the land. and somehow i am torn between company policies and the company target. if i give a few information to key sellers who i know can produce a lot of sale, we are able to meet target for sure by the time we launch the project. but of course company policies are telling me not to do it. so i don't. but still information is leaked and the very resourceful sellers are able to come up with materials so that they could present to their clients a project that will be up and coming, rising in different parts of Metro Manila. upon launching we have projects that we sell out in one week. so is it still a bad thing? because if someone leaked it, its company information that management had made strict guidelines not to share until the project launch date. but becuase somebody leaked it, then we are proud that we sold out. where do we determine the ethical side of that? is it still ethical? is there such a thing as right but not ethical?
