When an ASX insider buys up shares of the company that they are being paid to help run, investors usually sit up and pay attention.

No one knows better how a company is actually faring financially than the people who count the money as it rolls in and out. As such, when these insiders buy up shares, it is a useful sign to the markets that said company might represent a buying opportunity.

So today, let's talk about three ASX financial shares that are currently experiencing this very situation.

Three ASX financial shares that insiders are buying

Fleetpartners Group Ltd (ASX: FPR)

First up, we have fleet vehicle leasing company Fleetpartners. An ASX filing from 5 February last week shows that board member and non-executive director Mark Blackburn recently picked up a big tranche of shares.

According to the filing, Blackburn purchased an additional 10,989 Fleetpartners shares on 3 February last week. Blackburn indirectly purchased these shares in an on-market trade at an average price of $2.73 each through a superannuation fund, implying a total buy value of roughly $30,000.

This takes Blackburn's total stake in Fleetpartners to 22,929 shares, which would be worth around $64,660 at the current share price (at the time of writing) of $2.82.

Fleetpartners shares have had a rough 12 months, with the company down 13.5% since this time last year.

Hearts and Minds Investments Ltd (ASX: HM1)

Next, let's discuss ASX listed investment company (LIC) Hearts and Minds Investments. An ASX notice from last week revealed that Hearts and Minds board member and director Guy Fowler OAM has recently made a big investment in the company.

The ASX filing shows that Fowler indirectly bought (again, through a super fund) an additional 63,920 Hearts and Minds shares on 3 February in an on-market trade. The director paid an average price of $3.26 for these shares, implying a buy value of $208,597.

This takes Fowler's stake in Hearts and Minds to just under 1.39 million shares, which would be worth approximately $4.74 million at the current share price of $3.41.

The Hearts and Minds share price has risen by 31.8% over the past 12 months.

BKI Investment Company Ltd (ASX: BKI)

Finally, we have another LIC to discuss in BKI Investments. This offshoot of Brickworks Ltd (ASX: BKW). In BKI's case, we have a 4 February ASX filing that reveals independent non-executive director Ian Thomas Huntley has recently gone on a bit of a buying spree.

The notice tells us that Huntley indirectly picked up an additional 286,000 BKI shares over 29, 30 and 31 January last month, through a private company called Huntley Group Investments Pty Ltd.

Huntley spent a total of $498,679 on these shares, implying an average buy price of $1.74 per share. This takes Huntley's total investment in BKI up to 11.87 million shares, or $20.3 million.

BKI Investments shares have stagnated over the past 12 months, slipping by 3.01% since this time last year.
